Unit Forge Converter

Description

I built UnitForge because every unit converter I tried was either full of ads, locked basic units behind a paywall, or just got the math wrong. UnitForge is different. Pay once, use forever. No ads. No subscriptions. No tracking. No accounts. It just works. What you get: - 40+ conversion categories — from everyday (distance, weight, temperature) to engineering (viscosity, thermal conductivity, torque) to medical (blood glucose, HbA1c, cholesterol) - Cooking conversions that actually work — 1 cup of flour ≠ 1 cup of sugar. Select your ingredient, get the right weight. 25+ ingredients with USDA-sourced density data. - Wrench & socket size finder — enter a metric size, get the closest SAE match above and below (and vice versa). No more guessing in the garage. - Mixed unit display — see results as "5 ft 10 in" instead of "70 inches" or "3 lb 6 oz" instead of "54 oz" - Decimal precision control — set 0 to 10 decimal places in Settings - Dark mode — full support with auto/light/dark toggle - Zero data collection — we don't use analytics, don't make network requests, and have no idea how you use the app - Works offline — every conversion is computed on-device All conversion ratios are sourced from NIST, BIPM, and USDA, with 770+ automated tests ensuring accuracy.
